REPONSE is an integrated strategy to know the response of the biotic environment structure and the changes of the particulate matter dynamic, caused by the disturbance of fishing activity. This is a case study for biological and physical geological interactions.
This research is focused on providing new perspectives and management options to the CFP in order to achieve sustainable fisheries and of protection of biodiversity, a widely recognised problem in moving towards ecosystem-based management in fisheries.
The main objective is to obtain more knowledge on mid- and long-term effects to different regimens of fishing trawl perturbation on the seabed. The study will be performed in fishing grounds off European coasts: the North Sea, Irish Sea and Mediterranean Sea.
The specific objectives, estimation of changes in sedimentologic process, benthic and fish community, estimation of secondary production of the lower trophic levels, and analysis of the synthesis and integration of the results, will be achieved with six multudisciplinary workpackages.
The main achievement is related to understanding how long it takes for the benthic community to recover and what is its response to fishing activity, and the consequences of the sediment resuspension caused by trawlers.
The integration of environmental considerations in fisheries policy will benefit not only the environment but also the fishing sector, because fish resources need healthy marine ecosystems to flourish.
RESPONSE has as a fundamental goal to achieve sustainable fisheries and to explore measures of protection of biodiversity on marine communities.
The main scientific objective of RESPONSE is to know the mid- and long-term effects of fishing perturbation on the seabed by considering two main strategies of analyses:
1) cessation of fishing activity
2) different levels of fishing activity.
The specific research objectives of RESPONSE will be achieved by progressively developing the following scientific programme:
- To identify Appropriate Study Areas (ASA).
To define the spatial and temporal variability of different regimes and trawl activity in these ASA (Part of WP1).
- To estimate the fishing activity and fishing effort in the ASA during a whole year:
(i) spatial distribution and temporal variability of the trawl fleet
(ii) trawl tracks.
(iii) historical data sets of spatio-temporal distribution of fishing effort.
(iv) Correlation between fishing effects and existing/historical data on benthic communities (Part of WP1).
- To analyse the physical and biological response of the benthic ecosystem to different regimens of fishing activity in the ASA (Part of WP2 and WP3).
- To establish the energy flow in marine ecosystem by estimates the secondary
production of suprabenthos and infauna in the ASA (WP4).
- To combine the results as synthesis and recommendations (WP5).
The main achievement of RESPONSE will be to relate the recovery of the benthic community to the impact of commercial fishing activity and the consequences of the sediment resuspension caused by trawling.
The results of the project are expected to contribute in the development of a Common Fishery and Environmental Policy in the implementation of fishing regulation. They can help elucidate the potential effectiveness of:
. Using different time limited closure periods
. The most appropriate level of fishing effort
The project will provide information on the variability and resilience of marine ecosystems, especially for marine communities relevent to fisheries. This information may help determine the best times to close fishing grounds to allow benthic ecosystems to recover.
